2 Preparedness Emergency Response ESSENTIAL PILLARS OF EARTHQUAKE DISASTER RESILIENCE ESSENTIAL PILLARS OF EARTHQUAKE DISASTER RESILIENCE

3 EVERY TIME AN EARTHQUAKE DISASTER OCCURS, WE HAVE NEW KNOWLEDGE TO ADD TO OUR “BOOKS OF KNOWLEDGE” ON EMERGENCY RESPONSE

4 BREAKING NEWS August 24, 2014

5 THE MAGNITUDE 6.0 NAPA VALLEY, CA EARTHQUAKE 3:20 AM, AUGUST 24, 2014 Strongest in area since the M 6.9 1989 Loma Prieta Quake, BUT about 1/30 th the energy release

6 LOCATION: AUGUST 24 NAPA VALLEY EARTHQUAKE

8 USGS’ SHAKE MAP: AUGUST 24 NAPA VALLEY EARTHQUAKE

9 AUGUST 24: EARLY REPORTS OF SOCIOECONOMIC IMPACTS Local damage to buildings and houses, injuries, but no deaths (yet) Damage to contents Loss of Power Damage to Highway 12 Local fires Aftershocks

10 GLOBAL AN D LOCAL CONTEXTS

16 THE GOAL: DEMANDS ON COMMUNITY DEMANDS ON COMMUNITY EARTHQUAKE DISASTER RESILIENCE: CAPABILITIES OF COMMUNITY

17 REALITY: UNANTICIPATED DEMANDS ON COMMUNITY LACK OF EARTHQUAKE PREPAREDNESS INSUFFICIENT PREPAREDNESS OF COMMUNITY

18 REALITY: URGENT DEMANDS ON COMMUNITY LACK OF EMERGENCY RESPONSE CAPABILITY INSUFFICIENT CAPABILITY TO RESPOND TO DEMANDS ON COMMUNITY

19 WHAT IS EARTHQUAKE PREPAREDNESS? A state of readiness on individual, urban, sub-regional, and national scales that is sufficient to keep the expected and unexpected effects of an earthquake from causing a disaster

20 ANTICIPATION IS THE KEY TO PREPAREDNESS Strong ground shaking Tsunami wave run up Liquefaction Landslides Aftershocks Vulnerabilities

21 STRONG GROUND SHAKING

22 GROUND SHAKING CAUSES SOCIAL AND ECONOMIC LOSSES

23 AS COMMUNITY PREPAREDNESS INCREASES, SO DOES PROTECTION OF BUILDINGS AND INFRASTRUCTURE

24 WHAT IS PROTECTION? A legally mandated state of planning and verified robustness, strength, and ductility for important buildings and essential - critical infrastructure to prevent loss of function

25 WHAT IS EMERGENCY RESPONSE All of the scripted and unscripted heroic and historic responses during the “race against time” after a quake to save lives and protect property

26 KEY ELEMENTS OF PREPAREDNESS Know your seimic activity (i.e., Seismicity ) Know your fault zones Know your Vulnerabilites

27 FAULTS

28 THE USA’S MOST NOTABLE PLATE BOUNDARY FAULT ZONE San Andreas Fault 600 Miles long Source of M8 Earthquakes in 1847 and 1906

29 THE USA’S OTHER NOTABLE PLATE BOUNDARY FAULT ZONE The Juan De Faca Plate Subducting beneath Wash and Oregon Potential for M9.0

30 ONE OF THE USA’S TWO NOTABLE INTRA-PLATE FAULT ZONES Wasatch Fault, Utah 250 Miles long Potential source of M7.0-7.5 earthquake

31 ONE OF THE USA’S TWO NOTABLE INTRA-PLATE FAULT ZONES New Madrid Seismic ZoneNew Madrid Seismic Zone Source of four (4) M* earthquakes in 1811--1812Source of four (4) M* earthquakes in 1811--1812

32 Community preparedness and emergency management response increases as the community’s capability to anticipate what will increases

33 EARTHQUAKE SCENARIOS A DISASTER RISK REDUCTION TECHNIQUE FOR USE IN ANY EARTHQUAKE-PRONE AREA

37 NORTHERN CALIFORNIA SCENARIO (developed in 2008) BASED ON INTEGRATED KNOWLEDGE FROM MONITORING, RESEACH, AND POSTEARTHQUAKE STUDIES SINCE APRIL 1906

38 NORTHERN CALIFORNIA: WHAT NEEDS TO BE ANTICIPATED? How likely is a damaging earthquake to occur? Where and when will it occur? How big will it be? How strong will its potential disaster agents be?

39 The Bay Area is prone to large earthquakes because it straddles the boundary between two major tectonic plates — the North American and Pacific plates.

44 Much of the stress release happens on the San Andreas fault, but some of it is relieved by the Hayward fault and other smaller parallel faults.

45 Because of its location in the densely populated Bay area of 7 million people, a Hayward fault quake is likely to cause worse societal impacts than a San Andreas quake and be one of the nation's largest natural disasters.

47 DAMAGEDAMAGE PHYSICAL EFFECTS CAUSE SOCIETAL IMPACTS AND RISK COLLAPSECOLLAPSE LOSS OF FUNCTION ECONOMIC LOSS RISKRISK

48 WHAT NEEDS TO BE ANTICIPATED (Continued)? What kinds of buildings are at risk? What kinds of basic, essential, and critical infrastructure are at risk? What are the physical vulnerabilities?

49 Potentially affecting 5 million people, a Hayward fault quake damages homes, schools, senior centers, hospitals, businesses, the Bay bridge, and the campus of University of California, Berkeley.

50 WHAT NEEDS TO BE ANTICIPATED (Continued)? What are the social vulnerabilities? What is the likely damage distribution? What are the HAT ARE THE LIKELY CASUALTIES, SOCIO- ECONOMIC, AND ENVIRONMENTAL IMPACTS?

51 Damage will be extensive to buildings and infrastructure. The region's transportation infrastructure and water delivery systems are expected to take a major hit in a M7.0 or greater earthquake.

52 A M7.0 earthquake on the Hayward fault will cause an estimated $210 billion dollars in damage.

53 DAMAGE: AUGUST 24 NAPA VALLEY EARTHQUAKE

56 CONCLUSION EVERY TIME AN EARTHQUAKE DISASTER OCCURS, WE HAVE NEW KNOWLEDGE TO ADD TO OUR “BOOKS OF KNOWLEDGE” ON ANTICIPATING FUTURE IMPACTS
